Electromagnetics, RF and Microwaves

Description

The research program in applied electromagnetics covers a variety of topics that address current commercial, civil, and military needs. Specifically, our interests include active circuits and antennas for communications and radar, theoretical and numerical techniques for analysis of high-frequency circuits and antennas, RF photonics, artificial electromagnetic materials, electromagnetic remote sensing, etc. Our applications cover a broad frequency range, dc to optical.

Facilities

Microwave/RF/EM Teaching Laboratory: A variety of undergraduate and graduate courses share this laboratory with over 100 students per year. The lab is equipped with several automatic vector network analyzers, a dozen of microwave/RF sources, power meters and sensors, oscilloscopes and standard electronics equipment, as well as time-domain reflectometers. A small computer-controlled anechoic chamber dedicated to teaching occupies one part of the lab. Circuits can be fabricted in the lab using etching technology.

Current Research Support

Research support is provided by the National Institute of Standards and Technology, Office of Naval Research, U.S. Department of Defense, U.S. Air Force, National Aeronautics and Space Administration, National Science Foundation, National Oceanic and Atmospheric Administration, U.D. Department of Energy, and Wyle Laboratories. Research assistantships funded by these sources are available to qualified students. Fellowships are available for U.S. citizens from Lincoln Labs, and augmentation thesis fellowships are available for study abroad (currently Germany, Spain, Argentina, the Netherlands, and France).
